The SIBO breath test is not available at LifeLabs and Dynacare. Your test kit will be analyzed by the University Health Network in Toronto.

Receive your test kit and requisition in the mail 1 week after placing your order. Collect your sample and call the number provided for prepaid shipping and pickup by Purolator.

The kit contains a lactulose powder, which you mix with water and drink.

I strongly recommend performing the full 3-hour-long collection (rather than the 2-hour option).

A preparation diet must be followed 24 hours before the test. See the diet here: https://www.breathtests.com/knowledge-center/what-to-eat-before-sibo-test/
